Patented July 11, 1933 HARRY T. B OOTH, OF FREEPORT, NEW YORK FLYING MACHINE Application filed March 30,

This invention relates to flying machines and particularly to the motive power thereof. It has for its object the providing of power to drive the propeller shaft mounted above the top or deck of an airplane from an engine mounted low down in the fuselage or hull thereof.

it seeks to do this by providing a power tower requiring no support at the uppermost parts thereof, being a self contained unit. Instead of throwing the strain on the wings as is usual in devices of this kind, the power tower herein contains within itself all that is necessary to successfully hold the revolving propeller steady normally against torsion and bending. However if desired means may be employed to hold the power tower against fore and aft or sideways movement.

Other objects and advantages of the present invention will be apparent from the fol lowing description, reference being had to the accompanying drawing wherein the preferred form of embodiment of the invention is clearly shown, and in which similar nu- 3i merals of reference denote similar parts throughout the several views.

Figure 1 is a front elevation of the invention.

Fig. 2 is a side elevation thereof.

Fig. 3 is a section of the power tower taken along the line 3-3 of Fig. 1.

Fig. 4 is a section of the power tower taken along the line 4.- l of Fig. 1.

F 5 is a section of the stanchion taken along the line 55 of Fig. 1.

The invention is constructed and operated substantially and preferably as follows:

1 is the hull or body of the fuselage or boat, 2 the step board in the hull, 3 a bracket, 1

" the motor, 5 the fly wheel thereof, 6 the starter, and 7 a nut screwed into the top of the flywheel. A bracket or bridge 10 spans he flywheel 5 and is screwed thereover, setting on the streamlined stanchions or uprights 11 and held in place by the bolts 12 passing therethrough, a section of 11 and 12 being more particularly shown in Fig. 5.

In the said nut 7 is securely fastened the upright drive shaft 13 carried in tube 14 and 53 ending in the bevel pinion 15 meshing in 1931. Serial No. 526,168.

bevel wheel 16. The said shaft 13 is mounted inside the hollow streamlined casing 17; and fore and aft of 13 are the long bolts 18. A steady rest 19 is mounted intermediate 10 and 25.

A head or helmet 21 sets over the casing 17 and the said long bolts are screwed therein as at 22 making a unitary drive for upholding the gears 15 and 16. Inside this head are the said gears, the former on the said'shaft 13 as aforesaid, and the latter on the cross or propeller shaft 23. Ballbearings 24: and 25 hold the shaft 13 in alignment and ball bearings 26 and 27 hold the said cross shaft 6 23. 5

At the outer end of said cross shaft is the propeller 30 held in the usual way as at 31, 32 and 33 with nut 34..

As can be seen the shaft 23 needs no other support than the head 21 held rigidly by bolts 18 to the bracket 10, which in turn is fixedly fastened directly to the top of the motor a as at 9. This obviates tying the said head, with its propeller shaft, to any other F portion of the airplane as to the wings for instance, and thereby transmitting the vibration of the propeller to the same. The power tower is a unitary fixture and can be placed anywhere fore or aft in the fuselage without regard to the position of the wings, tail or the like. i

As my invention is in some of its aspects generic, I do not limit myself to the particular construction shown and described, but also contemplate the employment of such equivalents as fairly fall within the scope of the claims. A

In this connection I may state that while the device is shown mounted along the longitudinal axis of the hull adjacent the step, such a power tower can be placed on either side of the said center line if desired.

Therefore it should be understood that I may make various changes in the form, proportion. size and detail of the structure shown and described, and the number and position of certain elements used. without departing from the spirit of the invention.

I claim:

1. A flying machine comprising afuselage;

a power unit comprising a motor with a verlical shaft, an extension vertical shaft mounted in line with the said first mentioned shaft and driven thereby, gearing driven by the said last mentioned shaft, a propeller shaft and propeller driven by the said gearing; and means comprising a tube, a tube base bridge, a tube head, and a pair of long bolts mounted parallel with said vertical extension shaft and connecting the said bridge and head for fixedly holding the said shafts and propeller from vibrating without recourse to exterior support.

2.

3. A flying machine comprising a motor driving a vertical shaft, a fly wheel mounted on the shaf a support mounted over the flywheel and holding a standard fixedly thereon. a shaft in the standard mounted axially in line with tie motor shaft and driven thereby, a propeller shaft mounted at right angles to the second mentioned shaft and driven thereby, bearingsfor the last mounted shaft, and a pair of tension rods drawing the support and the bearings together.

4.' A flying machine comprising a motor driving a vertical shaft, a fly wheel mounted on the shaft, a support mounted over the fly wheel and holding a standard fixedly thereon. a shaft in the standard mounted axially in line with the motor shaft anddriven there by, a propeller shaft mounted at right angles to the second mentioned shaft and driven thereby, bearings for the last mentioned shaft. a hood holding the bearings and gears, and a pair of tension rods drawing the support and the hood together.

5. In combination with a flying machine, of a motor having an upright shaft, two uprights mounted in alignment with the shaft one on each side thereof, a bridge between the. uprights, a second bridge above the said first mentioned bridge, acolumn anchored on the bridges, ashaft therein driven by the first mentioneo shaft, .1 pair of long bolts running parallel. to the said second mentioned shaft and anchored on the said bridges and a propeller driven through gearing from the last mentioned shaft.

6. In combination with a flying machine, of a motor having an upright shaft, two up rights mounted one on each side of the shaft and in transverse alignment therewith, a bridge between the uprights, a column anchored on the bridge, a shaft therein driven by the first mentioned shaft, bearings for the last mentioned shaft, two tension rods connecting the bridge and bearings, and a propeller driven through gearing from the last mentioned shaft.

7. In combination with a flying machine, of a motor having an upright shaft, two uprights mounted one on each side of the shaft,
